Question

$a=\frac{1}{2}×b×h$
a triangle has base 10 cm and height 6 cm. what is the area?
10
120
30
60

Explanation:

Step1: Recall triangle area formula

The area of a triangle is given by $A = \frac{1}{2} \times b \times h$, where $b$ is the base and $h$ is the height.

Step2: Substitute given values

Substitute $b = 10$ cm and $h = 6$ cm into the formula:
$A = \frac{1}{2} \times 10 \times 6$

Step3: Calculate the result

First compute $10 \times 6 = 60$, then multiply by $\frac{1}{2}$:
$A = \frac{1}{2} \times 60 = 30$

Answer:

30 cm² (corresponding to the green option with value 30)
